| Abstract | Cytoplasmic male sterility (CMS) -associated genes are located in the mitochondrial genome whereas restorer of fertility (Rf) genes are located in the nuclear genome. Two major restorer gene loci of Wild abortive-CMS (WA-CMS), Rf3 and Rf4, are required for the production of viable pollen. The Rf4 locus of indica rice cultivars were reported, which contains four RNA-binding pentatricopeptide repeat protein (PPR) encoding genes. Preliminary sequence analysis of reported PPR gene at Rf4 locus from maintainer and restorer lines revealed the difference in size of protein only PPR10 protein that resulted from single nucleotide polymorphism (SNP). In this study, PPR10 gene was isolated from four Thai rice cultivars by Polymerase Chain Reaction (PCR) of genomic DNA. The nucleotide sequences of cloned PPR10 gene from Khao Dawk Mali 105, Nahng Mon S-4, Pathum Thani 1 and Suphan Buri 1 were analyzed by ClustalX program. One of fifteen SNPs at position 1,392 caused nonsense mutation and classified PPR10 protein into two groups by the length. Tetra-primer amplification refractory mutation system-polymerase chain reaction (ARMS-PCR) is fast, reliable and low cost. Then, four primers of ARMS-PCR were developed to use as an allele-specific DNA marker for Rf4 locus. The tetra- primer ARMS-PCR products of five maintainer cultivars and four restorer cultivars were G allele (416 bp) and T allele (242 bp), respectively. Therefore, tetra-primer ARMS-PCR could be allele specific PPR10 gene marker and used to identify maintainer and restorer Thai rice cultivars of WA-CMS. These allele-specific PPR10 gene markers will be used for germplasm genotyping and hybrid rice breeding program. |
